Description

Technical Field

[0001] The utility model relates to the technical field of electric screwdrivers, in particular to an electric screwdriver with adjustable speed. Background Art

[0002] Electric screwdrivers are one of the indispensable tools in today's industrial production. In the actual production process, the same production line may need to lock different screws. The torque and speed required for locking different screws are different. Therefore, enterprises often need to equip multiple electric screwdrivers of different specifications to meet production needs, which invisibly increases production costs. Most of the existing electric screwdrivers adjust the speed by pressing and turning buttons with different depths and degrees. Screws of different materials and thicknesses require different tightening or loosening torques. This speed adjustment method of electric screwdrivers may not be suitable for all types of screws, and it is not convenient to use, especially in precision working environments that require fine control of torque. Especially for some fragile materials or precision parts, too high a speed may cause damage to the screws, thread stripping or component damage, while too low a speed may lead to low work efficiency or even failure to complete the tightening task.
